I want to make a biological group of creatures where there is an absolute alpha creature that their lower kin cannot ever harm due to a mental prohibition. This would be equivalent to Asimov's first law of robotics - a lower kin may not harm their alpha or through inaction allow their alpha to come to harm, extended to also prevent them to do rebellion/revolution against their alpha even against this lower kin will.
The alpha cannot control their lower kin beyond this single restriction - they may not remote control the lower kin as a biological drone nor can they even give an order that must be obeyed beyond that restriction.
The concept is a bit similar to the powers of the dragon king in the second movie How to Train Your Dragon but more limited - there the Alpha could directly remote control other dragons like drone.
here a link to gif image to help imagine it better (imgur reject it)
and Here is a description of the dragon controlling ability in the link, for ease of search.
“ He who controls the Alpha, controls them all. [src] ” — Drago Bludvist The force of an Alpha
According to Dragons: Rise of Berk, Bewilderbeasts use their eyes and ultrasonic sounds to control dragons' minds. This was shown in the second movie, the Bewilderbeast's bony spines on its head were rapidly vibrating while the pupils on its eyes narrowed into slits, making it seem more likely, plausible, and believable that they are what broadcast the ultrasound.
the creatures, both alphas and lower kin, have intelligence comparable to humans.
the creatures are not insects, they are vertebrate and have a brain and not cold blood (I am not decided yet whether they should be warm blooded or both like dinosaurs, I forgot the correct english term for it)
the lower kin creatures vary considerably - some favour/specialist in strength or size, some prefer speed, some prefer maneuverability or agility, some prefer cunning, etc, each with their own pro and cons due to that.
the alpha is not necessary to be the biggest either, in fact there are many lower kin that are bigger than the alpha due to specialism build, but the alpha is more of a jack-of-all-trades build but still higher compare to the common one and just a bit bellow compare to the specialist build/stats.
I do not want to use pheromones as the mechanism for this control so please do not provide this as an answer. Similarly, symbiotic or parasitic creatures such as fungi or worms are not acceptable. I want the mechanism to be part of the creature's organs (especially internal organs if possible).
not just simply be based on psychology/society either, like ancient ancestor trauma or intimidation or instinct or tradition or base of simple cunning.
I do not mind the ultrasonic sound method like the dragon king in the link, if it is scientifically or biologically possible, though I prefer no antenna for my creature, but I wonder how it would work with the lower kin organs to be able to be mind controlled.
The mind control ability should not also affect another alpha, since I want the situation to be that only an alpha can fight against another alpha.
the mind control cannot be based on sexual organs or gender.
Is there a scientific or biological way to achieve this?
feel free to correct my grammar or the tag to the appropriate one.
